To all whom it may concern."

Be it known that l, Louis Hess, a citizen of the Empire of Germany, andresiding at Darmstadt, Germany, have invented certain new and usefulImprovements in Beer- Faucets, of which the following is aspecification.

My invention relates to faucets for tapping beer, and a primary objectis to provide an improved beer-faucet which enables beer not only topass Without foam into a glass, pitcher or other vessel, and fill thesame to any desired height, but also to. be supplied in the form offroth or foam. The foamless discharge of the beer into the vessel isbrought about by t-he beer being led between annular members havingintervening narrow spaces for the passage of the beer, so that the beerhas to overcome great frictional resistance between the walls of theannular members whereby the pressure of the beer becomes graduallyreduced, while foaming is caused in my improved faucet owing to the beerpassing through a bell-mouthed nozzle and then entering an outlet duct,where air cannot mix with the issuing liquid, but only carbonio acidbubbles can be formed.

One illustrative embodiment of my invention is represented by way ofexample in the accompanying drawing, wherein :w

Figure 1 is a longitudinal section, and Fig. 2 a similar section withthe spigot in another position; Figs. 3 and 4 are horizontal sectionsthrough the faucet with the spigot in different positions, and Fig. 5 isa side elevation of the bottom of the spigot.

Referring to the drawing, the faucet comprises a casing 2 having abranch pipe 3 and containing the rotatable spigot 4. This spigot has abore 5 constituting a chamber and contains a concentric tube-like member6 so arranged that an annular space 7 is formed between it and thespigot. In the space surrounded by this member 6 is arranged theupwardly tapering, concentric, hollow cone 8. The bottom of the cone 8rests on the cap 10 of the spigot, the cylindrical portion 22 of saidcap being screwed over the reduced portion 11 of the spigot 4. A nut 13having lugs 12 is screwed onto the lower end of the cone 8 and supportsa second tube-like member 14 in such a manner that between the twomembers 14 and 6, as well as between the member 14 and the cone 8 theannular spaces 17 and 18 are respectively formed and serve as channelsfor the beer. The cone 8 opens aboveinto a duct 16 forming therewith achamber which, in the position of the spigot shown in Fig. 2, isconnected with the inlet pipe 3. The cap 10 has within it a duct 19which constitutes an outlet for the foamed beer and opens inwardly intoa bell-mouthed nozzle 20, whose section at the constricted portion isabout 1/50 of the section of the inlet pipe. The reduced portion 11 ofthe spigot, as well as the cylindrical portion 22 of the cap 10 isprovided with a slot 21, 29, respectively, as an outlet for the beer.The spigot 4 is also provided with a bore 23 (Figs. 3 and 4) containinga pin 25 having a head 24 which is pressed toward the casing 2 by meansof a spring 26. A hole 27 in the casing is adapt edto receive a portionof said head 24 and in this manner the spigot 4 is secured when it isturned into the closed 7 position, as shown in Fig. 4.

In order to tap the beer the spigot is rst of all t-urned into theposition illustrated in Figs. 1 and 3. The consequence is that the beerentering from the pipe 3 passes into the annular chambers or spaces 7,17, 18, flows through these with gradually reduced pressure into thespace 30 whence it runs through the slot 29 into the vessel held below.Before this vessel is quite full, the spigot is turned into the positionshown in Fig. 2. The beer then Hows through the cone 8 and enters thebell-mouthed nozzle 20. Beyond the constricted portion of the same, thepassage therein is enlarged to be of the same section as the duct 19,and the beer therefore enters the duct at a high speed and consequentlywith a small pressure, in consequence of which the carbonic acid isliberated, which causes the beer to foam. Since air is quicklydischarged from the duct 19 by the passage of the beer, the foam soformed contains only the gas absorbed in the beer, c'. e. carbonio acidgas. The foamed beer flo-wing from the duct 19 then produces the desiredcovering of froth on the beer previously discharged.

1. In a beer faucet, the combination with a casing having a branch pipe,a spigot rotatable in the casing and having two separate chambers,eachchamber having an inlet adapted to be connected with said pipe,themllO one chamber having an outlet duct and the other an outlet, anozzle mounted in the spigot between the former chamber and its outletduct, and one or more members dividing the latter chamber into narrowpassages located between the members and the walls of the latter chamberand connecting the in- Y let of the latter chamber with the outletthereof.

2. In a beer faucet, the combination with a casing having a branch pipe,a spigot rotatable in the. casing and having a larger and a smallerchamber, each chamber having an inlet adapted to be connected with saidpipe, the smaller chamber having an outlet duct and the larger anoutlet, the larger chamber being an annular chamber concentricallysurrounding the smaller one, a nozzle mounted in the spigot between thesmaller chamber and its outlet duct, and a plurality of concentric,tubular members dividing the larger chamber into narrow annular passageslocated between the members and the walls of the larger chamber andconnecting the inlet of the larger chamber with the outlet thereof.

3. In a beer faucet, the combination with a casing having a branch pipe,a spigot rotatable in the casing and having a larger and a smallerchamber, each chamber having an inletl adapted to be connected with saidpipe, the smaller chamber having an outlet duct and the largeran out-letslot, said duct and said slot opening in opposite directions, a nozzlemounted in the spigot between the smaller chamber and its outlet duct,and a plurality of concentric, tubular` members dividing the largerchamber into narrow annular passages located between the members and thewalls of the larger chamber and connecting the inlet of the largerchamber with the outlet thereof.

In testimony whereof, I aiiX my signature in the presence of twowitnesses.
